METHOD OF OPERATING FIRE-ENGINES.

Specification of Letters Patent No. 14,089, dated January 15, 1856.

To all whom t may concern:

Be itknown that we, JOHN P. OowlNG, PHrLo CowrNc, and GEORGE CowING, ofSeneca Falls, in the county of Seneca and State of New York, haveinvented certain new and useful Improvements in Fire-Engines; and we dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, in which- Figure l, is a verticalsection of our improvement, (m), (m), Fig. 2, showing the plane ofsection. Fig. 2, is a horizontal section of ditto, (y), (y), Fig. l,showing the plane of section. Fig. 3`is a longitudinal section of thebox underneath the bed plate and cylinders.

Similar letters of reference indicate corresponding parts in the severalfigures.

The nature of our invention consists in the arrangement of the mechanismemployed for operating the pistons as will be presently shown anddescribed.

To enable others skilled in the art to fully understand and constructour invention, we will proceed to describe it.

A, represents a-bed plate on which two cylinders B, B, are secured, saidcylinders being placed side by side.

O, represents a frame formed of the uprights (a), (a), having theirupper ends connected by a cross piece (b) see Fig. l.

D, represents a rock shaft which is fitted within bearings (c), (c), onthe bed plate A, and E, E, are lever frames which project from oppositesides of the rock shaft. To the center of the shaft D, an arm F, isattached having two rods (d), (d), attached to its upper end. The outerends of the rods (d), are attached to toggles G, G. The upper levers(e), (e), of the toggles are attached to pendents (f), (f), which aresecured to the cross piece And t-he lower ends of the lower levers (g)of the toggles are attached to piston heads H, H, which are tted withinthe cylinders B, B.

I, I, are the piston rods which work through guides J, J, attached tothe upper end of the cylinders. The guides J, J, are bars which extendacross the centers of the upper parts of the cylinders. The ends of thebars, J, are attached to rings, K, which are equal in diameter to thecylinders, and

the rings are secured upon the upper ends of the cylinders in any propermanner.

Circular apertures (71,), (71,), are made through the bed plate A,directly underneath the cylinders. The diameters of these apertures areequal to that of the bores of the cylinder. To the under side of the bedplate A, there is attached a box L, which has two inclined partitions(i), (i), placed in it. The cylinders B, B, communicate with the spacebetween the two inclined partitions. This space is divided into twocompartments by a partition (j), and each partition (i), has a brassvalve seat (la), fitted snugly to it. These seats (7c), having valves(Z), attached to them see Fig. 3, a suction and force valvecommunicating with each compartment at each side of the partition Thevalve seats (7o), are planed perfectly smooth so that they may beproperly fitted to the partitions (z'), (z'), and are secured to thepartitions by bolts or in any proper manner. The box L, and partitionsmay be constructed of any kind of metal As the lever frames E, E, areoperated the pistons H, I-I, will be moved up and down within thecylinders by means of the toggles G, G, one piston moving upward whilethe other is moving downward and the water is drawn into thecompartments underneath the cylinders as the pistons move upward and isejected or forced from said compartments as the pistons move downward.By the use of the toggles G, G, \the pistons are operated with a smallex penditure of power and by having the valves and valve seats formed ofbrass and attached to the partitions (z'), (2'), as shown durability isobtained and also a perfect operation of the valves.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent, is,

The arrangement of the toggles G, G, shaft D, arm F, and rods (d) (d)for op erating the pistons H, H, substantially as shown and described.
